【Detailed ways】

With reference to the drawings, the aforementioned and other technical contents, features and effects of the invention will be clearly presented in the following detailed description of the preferred embodiments.

As shown in Figure 1, according to the design concept of this creation, a kind of ventilation device for shoes is provided, including:

Several first springs 40 are installed in the combination of the first part 10 and the second part 20, and several second springs 50 and spherical pistons 60 are installed in the combination of the second part 20 and the third part 30 by a screw 70 solid, of which:

The first part 10 is a circular box cover formed of rubber material. The box cover has a front side 11 and a back side 12. On the circumference of the back side, a cylindrical first box wall 121 is erected. A second box wall 122 hangs vertically from the inner diameter of the first box wall, and a groove 123 is formed between the first box wall and the second box wall, which can be buckled with the cylindrical part 211 of the second part 20 inside and outside. Several first protrusions 124 are arranged in a surrounding state in the inner diameter of the two box walls, and the first protrusions are designed to be nested with the first spring 40 .

The second part 20 is shaped like a circular box seat, which is a supporting mechanism of the first part 10, and includes an upper surface 21 and a bottom surface 22, and the inner diameter of the upper surface is vertically provided with a groove that can be buckled into a groove 123 The cylindrical part 211, such as the inner diameter of the cylindrical part, has several second convex posts 212 corresponding to the first convex post 124, and the second convex post is a supporting structure for positioning with the first spring 40; in this creation , a rectangular body 23 protrudes from the central position of the upper surface 21, the combination mechanism of the third part 30 of the rectangular system, the rectangular body 23 is provided with a tubular suction pipe 231 or exhaust pipe 232 that can accommodate the second spring 50 The lower end of the suction pipe is provided with a hemispherical damper 2311 which can be supported by the spherical piston 60 for exhausting, or the lower end of the exhaust pipe is provided with an obstruction 2321 which can resist the second spring, such as a damper and an obstruction. Its extension all runs through the bottom surface 22 and communicates with the tubular holes 221, 222 protruding from the bottom surface. In this creation, the apertures of the tubular holes 221, 222 are smaller than the inner diameter of the suction pipe 231 or the exhaust pipe 232, thereby It can prevent the piston 60 or the second spring 50 from being unable to escape. The top surface of the rectangular body 23 is a step-like plane separated by an inclined surface 233. The step-like design is a fool-proof structure for combining with the third part 30 accurately and conveniently. There is a central hole 234, and the central hole interferes with a screw 70, which can fix the third part 30 on the top surface of the rectangular body.

The third part 30 is a combination mechanism of the rectangular body of the second part, which includes a top surface 31 and a bottom surface 32, and the bottom surface is a step-like high and low plane with a foolproof function formed by an inclined surface 321. The equal slope 321 and the high and low planes with fool-proof function coincide with the slope 233 and the step-like plane of the second rectangular body. The top surface 31 is separated from the bottom surface 32 to form a tubular perforation 33, and the lower port of the tubular perforation is respectively connected with the suction pipe 231 or the exhaust pipe 232 of the second part. The blocking portion 331 and the hemispherical stop portion 332 with the exhaust function, thereby making the aperture extending to the upper ports 3311 and 3321 smaller than the aperture of the tubular perforation 33, thereby making the device installed in the suction pipe 231 or exhaust pipe 232 The second spring 50 or the spherical piston 60 cannot escape outwards. In this invention, the blocking portion 331 and the restraining portion 332 can have the same structure, or can become mutual replacement structures according to corresponding structural changes. The third part is provided with a central hole 34 from the top surface 31 to the bottom surface 32. The central hole 34 is the corresponding structure of the central hole of the second part. The central hole allows a screw 70 to pass through, and the second part is connected by the screw. The three parts 30 and the second part 20 are firmly integrated into one body, so that the complete functions of air intake and exhaust of the valve mechanism are realized.

The assembly method of the ventilation device of a kind of shoes: the first step, install the second spring 50 and the spherical piston 60 in the suction pipe 231 or the exhaust pipe 232 of the second part 20, and then install the second spring 50 and the spherical piston 60 The three parts 30 are fastened to the rectangular body 23 of the second part 20, and then, a screw 70 penetrates the center hole 34 of the third part 30 to the center hole 234 of the second part, so as to interfere firmly. That is to say, the structure of the air valve with both suction function and exhaust function in the ventilation device is completed; in the second step, one end of several first springs 40 is placed on the first boss 124 of the first part 10 , the first part 10 is formed of a rubber material with contraction function, so the first spring 40 installed on the first protrusion 124 will not fall off naturally. In the third step, when fastening the first part 10 with the first spring 40 and the second part 20, it is necessary to align and position the other ends of the first springs 40 with the second boss 212, and then The first part 10 is fastened with the second part 20, so that the cylindrical part 211 of the second part 20 is completely inserted in the groove 123 of the first part 10, because the first part 10 is made of rubber material with elastic function Therefore, after assembly, the first part 10 will have the function of sealing and tightening the second part 20, thus forming an air pump and combining the function of the air valve to complete a ventilation device for shoes.

In summary, the above specific embodiment is only for the purpose of this case description, and this case can still be implemented in other ways, so those who are familiar with this technology can implement other changes that can be made according to this description without departing from the creative spirit of this creation. , can be covered by the scope of the patent application in this case.
